MSW5PM

Alarms, Buzzers, And Sirens Overview

The MSW5PM is a piezoelectric speaker and transducer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 2.7 V to 5.5 VDC with a current rating of 400 mA. The device produces a sound pressure level between 85 dBA and 95 dBA across a frequency range of 150 Hz to 4 kHz. It features an octagonal shape and utilizes solder pin termination for PCB mounting. The unit functions reliably in temperatures from -30°C to +55°C, with physical dimensions of 23 mm length, 13 mm height, and bulk packaging.

Alarms, Buzzers, And Sirens Feature Summary

• Integrated internal driver circuitry for direct signal input
• Solder pin termination compatible with standard PCB assembly

Alarms, Buzzers, And Sirens Applications

• Medical equipment audio indicators
• Industrial control panel signaling
• Consumer electronics alert systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix against the official datasheet to confirm exact acoustic output and electrical characteristics, as variations exist within the series. Confirm RoHS compliance status and lead times directly with authorized distributors prior to ordering. Ensure PCB footprint matches the specified solder pin configuration.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, high-output audio indicator is required for low-voltage DC applications. The wide frequency range supports both tone generation and voice-like alerts. Verify that the 400 mA current draw is supported by the target power supply and PCB trace capacity.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSW series of piezoelectric speakers designed for board-level integration. Unlike panel-mount buzzers, these units are optimized for direct surface mounting on printed circuit boards, providing a space-efficient solution for embedded audio signaling requirements in portable or dense electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains identical voltage ratings, current consumption limits, and mechanical mounting dimensions to guarantee compatibility with existing PCB layouts.
